Wax-Resin Composite for Cosmetic Adhesion and Sensory Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrocarbon resins, known for their excellent adhesion, are underutilized in cosmetics and pharmaceuticals due to their poor sensory properties when applied to skin, hair, and nails, leading to an occlusive film and discomfort.
Innovation Solution
A ternary or quaternary composite of hydrocarbon resin blended with waxes and an antioxidant is developed, which improves adhesion, rub-resistance, and flexibility while balancing sensory acceptability, by forming a hydrocarbon wax-resin composite that can be used in cosmetic and pharmaceutical formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hydrocarbon resin is used to improve adhesion, then adhesion is improved, but sensory properties deteriorate and an occlusive film is formed
Solution Approach 1:
The patent combines hydrocarbon resin with waxes and antioxidants to create a composite material. This merging allows the resin's adhesion properties to be balanced with the wax's ability to provide desirable sensory characteristics, resolving the contradiction between strong adhesion and good sensory properties.
Solution Approach 2:
The invention creates a composite material system consisting of hydrocarbon resin, wax, and antioxidant components. This composite approach allows the material to exhibit both the adhesion benefits of the resin and the sensory benefits of the wax, while the antioxidant ensures stability.
2Strength
If hydrocarbon resin is used to improve adhesion, then adhesion is improved, but the film becomes occlusive
Solution Approach 1:
By merging hydrocarbon resin with wax components, the patent creates a composite film that provides adhesion without the excessive occlusivity of pure resin. The wax-modified resin composite achieves a balance between adhesion and breathability.
3Object-affected harmful factors
If wax is added to modify adhesion properties, then sensory properties are improved, but adhesion decreases
Solution Approach 1:
The patent formulates a composite material where wax and hydrocarbon resin work synergistically. The resin component maintains adhesion strength while the wax component provides desirable sensory properties, achieving both goals simultaneously through proper formulation.
Solution Approach 2:
By adjusting the ratios and types of waxes and resins in the composite, the patent optimizes the balance between adhesion and sensory properties. The specific composition parameters are tuned to achieve both strong adhesion and good sensory characteristics.
4Stability of the object's composition
If resin is processed at high temperature to blend with waxes, then homogeneity is improved, but energy consumption increases and stability may deteriorate
Solution Approach 1:
The patent selects processing temperatures that are optimized for blending the resin and wax components effectively. By carefully controlling temperature parameters, the patent achieves homogeneous mixing while minimizing energy consumption and preventing degradation of the antioxidant and other sensitive components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite enhances the performance of final films on skin, hair, lashes, and nails by improving adhesion, flexibility, and stability, reducing the time required for resin solubilization, and increasing water-resistance, making it suitable for various cosmetic and pharmaceutical products.
Implementation Method 1
the hydrocarbon resin is first partially solvated with a hydrocarbon solvent to blend the waxes and hydrocarbon resin together in a homogenous mixture
Implementation Method 2
Through controlled evaporation of the solvent, solid granules via crystallization and semi-solid dispersions are produced
Implementation Method 3
An additional component, an antioxidant, is typically included to insure stability of the matrix for odor and chemical integrity
Implementation Method 4
Through controlled evaporation of the solvent, solid granules via crystallization and semi-solid dispersions are produced

AI summary
A method for producing a wax-resin composite comprises at least partially solvating a thermoplastic resin in a solvent to form a resin-solvent blend. The waxes comprise at least one of a first wax selected from the group consisting of crystalline polyethylene waxes, synthetic waxes, hydrocarbon waxes, petroleum waxes and mixtures thereof. The waxes also comprise a second wax selected from the group consisting of natural or synthetic waxes containing hydrocarbons or hydrocarbon-like structures. After blending and melting, the blended thermoplastic hydrocarbon resin and waxes are allowed to solidify. Solidification is followed by post-processing the wax-resin composite mixture to form slabs, pastilles, flakes or other forms. Post processing may comprise extrusion and chopping, molding, molding and chopping, droplet formation and solidification, pouring into a turbulent cooling airflow, or the like.
